  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
In the hair iron according to the present embodiment, the contact portion that comes into contact with the hair when the hair is clamped for treatment is formed from isotropic high-density graphite. Thereby, when a contact part is heated, far infrared rays will be radiated | emitted from a contact part. And the hair and scalp are warmed from the inside by the far infrared rays emitted from this contact portion.

  As shown in FIG. 1A, the hair iron 1 according to the present embodiment includes a first arm 21, a second arm 22, a first contact portion 41, and a second contact portion 42. The hair is clamped between the first arm 21 and the second arm 22 for treatment. Further, as shown in FIG. 1B, the hair iron 1 supplies power to the heater 71 that heats the first contact portion 41, the heater 72 that heats the second contact portion 42, and the heaters 71 and 72. And a power supply unit 8. Note that FIG. 1B is a cross-sectional view of a portion A1 surrounded by a broken line in FIG.

  Each of the first arm 21 and the second arm 22 has a long box shape. One end portion in the longitudinal direction of the second arm 22 (right end portion in FIG. 1A) pivots to one end portion in the longitudinal direction of the first arm 21 (right end portion in FIG. 1A) via the hinge portion 3. It is worn. Accordingly, the second arm 22 is configured such that the other end (the left end in FIG. 1A) approaches or moves away from the other end of the first arm 21 (the left end in FIG. 1A). It is free to move. As shown in FIG. 1B, an opening 21 a in which the first contact portion 41 is disposed is formed in a portion of the first arm 21 that faces the second arm 22. In addition, an opening 22a in which the second contact portion 42 is disposed is formed inside the second arm 22 at a portion facing the first arm 21. A power cord 6 connected to an external power source is led out from one end of the first arm 21 (the right end in FIG. 1A).

  The 1st contact part 41 and the 2nd contact part 42 are members which contact hair at the time of a treatment. The first contact portion 41 is disposed inside an opening 21 a provided in a portion of the first arm 21 that faces the second arm 22. The second contact portion 42 is disposed inside an opening 22 a provided in a portion of the second arm 22 that faces the first arm 21. The first contact portion 41 includes a base material 411 formed in an elongated plate shape from isotropic high-density graphite, and a DLC (covering a portion of the surface of the base material 411 exposed to the outside of the first arm 21). Diamond Like Carbon) film 412. The second contact portion 42 covers the base 421 formed in a long plate shape from isotropic high-density graphite and the portion of the surface of the base 421 that is exposed to the outside of the second arm 22. A DLC film 422. The base materials 411 and 421 are manufactured by a manufacturing method similar to the manufacturing method of “carbon molded body” described in, for example, a document: Japanese Patent Application Laid-Open No. 2012-100777. The DLC films 412 and 422 are formed by a CVD (Chemical Vapor Deposition) method or a vacuum deposition method. Further, the heat insulating member 5 is interposed between the first contact portion 41 and the periphery of the opening 21 a of the first arm 21. The heat insulating member 5 is also interposed between the second contact portion 42 and the periphery of the opening 22 a of the second arm 22. Thereby, the transmission of heat from the first contact portion 41 and the second contact portion 42 to the first arm 21 and the second arm 22 is suppressed.

  The heaters 71 and 72 are composed of ceramic heaters. The power supply unit 8 is connected to the heaters 71 and 72 via the conductive wires 81 and 82, and a direct current is supplied to the heater 71 via the conductive wire 81 and a direct current is supplied to the heater 72 via the conductive wire 82. . The power supply unit 8 includes a rectifying / smoothing circuit that converts alternating current supplied from an external alternating-current power supply via the power supply line 83 into direct current, and a step-down circuit that steps down the output voltage from the rectifying / smoothing circuit. The heaters 71 and 72 and the power supply unit 8 constitute a heating unit that heats the first contact unit 41 and the second contact unit 42.

  According to hair iron 1 according to the present embodiment, first contact portion 41 and second contact portion 42 have base materials 411 and 421 formed from isotropic high-density graphite. Accordingly, for example, the first contact portion 41 or the second contact portion is compared with a configuration in which the first contact portion and the second contact portion are dispersed in a base material of a ceramic powder material that is a far infrared radiation material. The amount of far infrared rays emitted from 42 can be increased. Therefore, the effect of warming the hair and scalp from the inside during the treatment is enhanced.

The density of ceramics such as alumina and silicon dioxide is about 2.2 [Mg / m ³ ] to 4.1 [Mg / m ³ ], whereas the density of isotropic high-density graphite is 1. 7 [Mg / m ³ ] to 2.0 [Mg / m ³ ], which is lower in density than ceramics. Therefore, for example, the weight per unit volume of the first contact portion 41 and the second contact portion 42 is reduced compared to a configuration in which the first contact portion and the second contact portion are formed of ceramics that are far infrared radiation materials. The Thereby, weight reduction of the hair iron 1 is achieved and there exists an advantage that the burden of the user who uses the hair iron 1 is reduced.

  Further, the DLC film 412 is exposed on the surface of the first contact portion 41, and the DLC film 422 is also exposed on the surface of the second contact portion 42. Thereby, when moving the position of the hair iron 1 in the state which clamped the hair with the 1st contact part 41 and the 2nd contact part 42, the sliding between the 1st contact part 41 and the 2nd contact part 42, and hair is carried out. Since the dynamic resistance is reduced, the hair iron 1 can be moved smoothly.

  Furthermore, when the hair iron 1 according to the present embodiment is mainly intended to warm hair and scalp from the inside by far infrared rays radiated from the first contact portion 41 and the second contact portion 42, Electric power supplied to the heaters 71 and 72 can be reduced. In this case, since the power supply unit 8 having a relatively small output can be employed, the power supply unit 8 can be downsized.

(Embodiment 2)
The hair iron according to the present embodiment has a function of heating a cylindrical contact portion that comes into contact with the hair during treatment, and curls or waves around the hair by winding the hair around the contact portion while the contact portion is heated. It can be attached. The contact portion is made of isotropic high-density graphite, and when the contact portion is heated, far infrared rays are emitted from the contact portion.

  As shown in FIG. 2A, the hair iron 201 according to the present embodiment includes a handle 202, a contact portion 241, a clip portion 242, a power supply portion 8, and a cap portion 209. Moreover, the hair iron 1 is provided with the heater 207 which heats the brush part 204, as shown to FIG. 2 (B). Here, power is supplied from the power supply unit 8 to the heater 207. As shown in FIG. 2A, the handle 202 is formed in a long box shape, and the power supply unit 8 is housed inside. A power cord 206 connected to an external power source is led out from one end of the handle 202 (lower end in FIG. 2A).

  The contact part 241 is cylindrical and contacts the hair during the treatment. One end portion of the contact portion 241 (the lower end portion in FIG. 2A) is fixed to the other end portion of the handle 202 (the upper end portion in FIG. 2A) via a heat insulating member 205. Thereby, the transfer of heat from the contact portion 241 to the handle 202 is suppressed. The contact part 241 has a substantially cylindrical shape. The contact portion 241 may have a cylindrical shape with an outer diameter of 5 cm and an inner diameter of 3 cm, for example. The contact portion 241 includes a cylindrical base material 241a formed from isotropic high-density graphite, and a DLC film 241b that covers the outer surface of the base material 241a. The formation method of the base material 241a and the DLC film 241b is the same as the formation method of the base materials 411 and 421 and the DLC films 412 and 422 described in the first embodiment.

  The clip part 242 is arrange | positioned at the side of the contact part 241, and presses hair against the contact part 241 at the time of a treatment. The clip part 242 includes a long pressing part 2421, a support part 2422, a hinge part 2423, and a lever 2424. The pressing portion 2421 has a shape curved along the side surface of the contact portion 241 as shown in FIG. The support portion 2422 supports the pressing portion 2421 and is fixed to the handle 202 via the hinge portion 2423. The pressing portion 2421 can turn around the hinge portion 2423. Further, a spring member (not shown) for urging the pressing portion 2421 in a direction of pressing the side surface of the contact portion 241 is connected. When the user presses the lever 2424 with a thumb or the like while holding the handle 202, the pressing portion 2421 turns around the hinge portion 2423 and is separated from the side surface of the contact portion 241. The pressing portion 2421, the supporting portion 2422, and the hinge portion 2423 are formed from a metal such as titanium. The lever 2424 is made of a resin material. In addition, the material which forms the press part 2421 and the support part 2422 is not limited to a metal, Isotropic graphite and carbon fiber composite material (It is obtained by sintering the mixture of carbon fiber and a resin material. You may form from the material containing graphite, such as C / C composite (Carbon Fiber Reinforced Carbon Composite) or anisotropic graphite.

  The heater 207 is composed of a ceramic heater and is attached to the inner surface of the contact portion 241. The power supply unit 8 is connected to the heater 207 as in the first embodiment, and allows a direct current to flow through the heater 207. The heater 207 and the power supply unit 8 constitute a heating unit that heats the contact unit 241. The cap portion 209 is fixed to the other end portion of the contact portion 241 (the upper end portion in FIG. 2A) via a heat insulating member 205.

  According to hair iron 201 according to the present embodiment, contact portion 241 has base material 241a formed of isotropic high-density graphite. Thereby, like Embodiment 1, the effect which warms the hair and scalp at the time of a treatment from the inside is strengthened. Further, similarly to the first embodiment, for example, the hair iron 201 can be reduced in weight as compared with a configuration in which the contact portion 241 is formed of ceramics. Further, the DLC film 241 b is exposed on the surface of the contact portion 241. Thereby, when the hair wound around the contact portion 241 is unwound, the sliding resistance between the contact portion 241 and the hair is reduced, so that the hair wound around the contact portion 241 can be unwound smoothly.

(Modification)
Although the embodiment of the present invention has been described above, the present invention is not limited to the configuration of the above-described embodiment. For example, like a hair iron 301 shown in FIG. 3A, a heat transfer unit 391 is interposed between the first contact unit 41 and the heater 71, and heat transfer is performed between the second contact unit 42 and the heater 72. The structure in which the part 392 intervenes may be sufficient. Note that in FIG. 3A, components similar to those in Embodiment 1 are denoted by the same reference numerals as in FIG. The heat transfer parts 391 and 392 are made of a metal such as copper or iron.

  In Embodiment 1, the example which has the base materials 411 and 421 in which both the 1st contact part 41 and the 2nd contact part 42 were formed from isotropic high density graphite was demonstrated. However, the configuration is not limited to this, and only one of the first contact portion 41 and the second contact portion 42 may have a portion formed of isotropic high-density graphite.

  In the hair iron 1 which concerns on Embodiment 1, the structure where the mutually opposing surface of the 1st contact part 41 and the 2nd contact part 42 was substantially flat was demonstrated. However, the shape of the mutually opposing surface of a 1st contact part and a 2nd contact part is not limited to this. For example, as shown in FIG. 3B, the surfaces of the first contact portion 541 and the second contact portion 542 facing each other may have a curved shape so as to be convex in a direction approaching each other. . Note that in FIG. 3B, the same components as those in Embodiment 1 are denoted by the same reference numerals as in FIG. The first contact portion 541 and the second contact portion 542 are obtained by coating DLC films 412 and 422 on the surfaces of base materials 5411 and 5421 having curved surfaces, respectively.

  About the hair iron 1 demonstrated in Embodiment 1, it extends in the transversal direction of the 1st contact part 41 and the 2nd contact part 42 to at least one of the surface of the 1st contact part 41 and the surface of the 2nd contact part 42. The structure in which the several groove | channel was formed may be sufficient. For example, like the hair iron 601 shown in FIG. 4A, the first contact portion 641 and the second contact portion 641 are formed on both the surface of the base material 6411 of the first contact portion 641 and the surface of the base material 6421 of the second contact portion 642. The structure in which the some groove | channel 6413, 6423 extended | stretched in the transversal direction of the contact part 642 may be formed. In addition, in FIG. 4 (A), about the structure similar to the hair iron 1 which concerns on Embodiment 1, the code | symbol same as FIG. 1 (B) is attached | subjected. Here, the depth and width of the grooves 6413 and 6423 are not particularly limited. In this hair iron 601, the positions of the plurality of grooves 6413 of the first contact portion 641 and the plurality of grooves 6423 of the second contact portion 642 are shifted from each other in the longitudinal direction of the first contact portion 641 and the second contact portion 642. ing.

  According to this configuration, the hair can be combed in a state where the hair is fitted inside the groove 6413 of the first contact portion 641 or inside the groove 6423 of the second contact portion 642, and the first contact portion 641 or the first contact portion 641 The contact area between the 2-contact portion 642 and the hair increases. Therefore, it becomes possible to warm hair more efficiently.

  About the hair iron 201 demonstrated in Embodiment 2, the structure by which the some groove | channel extended in the circumferential direction of the contact part 241 was formed in the surface of the contact part 241 may be sufficient. For example, a structure in which a plurality of grooves 7243 extending in the circumferential direction of the contact portion 7241 is formed on the surface of the contact portion 7241 as in a hair iron 701 illustrated in FIG. In FIG. 4B, the same reference numerals as those in FIG. 2A are assigned to the same configurations as those of the hair iron 201 according to Embodiment 2.

  According to this structure, hair can be wound around the contact part 7241 in a state where the hair is fitted inside the groove 7243 of the contact part 7241, and the contact area between the contact part 7241 and the hair is increased. Therefore, it becomes possible to warm hair more efficiently.

  In Embodiment 2, the example in which the contact portion 7241 is cylindrical has been described, but the shape of the contact portion 7241 is not limited to this. For example, the cylinder may have a polygonal cross section.

However, the present invention is not limited thereto, and for example, a power storage unit is provided, and the power supply unit 8 receives power supply from the power storage unit. Also good. In this case, since the hair iron can be used even in a place where there is no power supply facility such as an outlet, it is possible to provide a user-friendly hair iron.

  In each embodiment, the example in which the first contact portion 41, the second contact portion 42, and the contact portion 241 are formed from isotropic graphite has been described. However, the first contact portion 41, the second contact portion 42, and the contact portion are described. The material for forming 241 is not limited to this. For example, the 1st contact part 41, the 2nd contact part 42, and the contact part 241 may be formed from the carbon fiber composite material (carbon composite) or anisotropic graphite. Moreover, while the thermal conductivity of ceramics is 20 to 40 W / (m · K), the thermal conductivity of isotropic graphite is about 150 W / (m · K), and the thermal conductivity of anisotropic graphite. Is about 170 W / (m · K), and the thermal conductivity of the carbon composite is about 100 W / (m · K). Therefore, compared with the case where the 1st contact part 41, the 2nd contact part 42, and the contact part 241 are formed from ceramics, heat propagates to the 1st contact part 41, the 2nd contact part 42, and the contact part 241 whole. easy. Therefore, since the heating part in the 1st contact part 41, the 2nd contact part 42, and the contact part 241 can be made small, the heaters 71, 72, and 207 can be reduced in size, and the heaters 71, 72 are accordingly reduced. , 207, energy saving is achieved by reducing energy loss.
